Question about feature lines in Autodesk Civil 3D

molly_baar

How do you curve a feature line in Civil 3D? I want to make a nice looking feature line, but I can't seem to figure out how to curve it. Any tips?I'm just curious as to how others make their feature lines curve. I've seen some really nice looking feature lines, and I'm hoping to learn how to make mine look just as good!

There are a few ways to make a feature line curve. The most common way is to use the Curve command.

Select the feature line you want to curve.
Click the Curve button on the Modify tab.
Specify the start and end points of the curve.
Enter the radius of the curve.
Press Enter.

You can also use the Curve dialog box to create a curve.

Select the feature line you want to curve.
Right-click and select Curve Properties.
In the Curve Properties dialog box, select the Type tab.
Select the type of curve you want to create.
Enter the parameters for the curve.
Click OK.
